One end of the connecting rod lifting mechanism 4 is hinged to the push rod mechanism 3, and the other end is hinged to the shelf frame 1. Under the joint action of the push rod mechanism 3 and the connecting rod lifting mechanism 4, the shelf board 2 can be rotated around its rotation axis to form a certain inclination angle with the horizontal plane, so that the goods 5 (container) can automatically slide out of the shelf to the picking device under the action of gravity. After the picking is completed, the shelf board 2 can automatically return to the initial position under the action of its own weight.

[0034] Shelf board support beams 13 are provided on both sides of the shelf frame 1, and the width of the shelf board support beams 13 is greater than the width of the shelf frame vertical beams 16.

Under the thrust of the pushing rod mechanism 3, the connecting rods of the connecting rod assembly cooperate with each other to realize the lifting movement of the roller 45, so that the shelf board 2 in contact with the roller 45 rotates around the shelf board rotating shaft 21. When the shelf board 2 reaches a certain inclination angle with the horizontal plane, the goods 5 (container) placed on the shelf board 2 can automatically slide out of the shelf to the picking device under the action of gravity; after the goods 5 (container) are taken out, the force of the pushing rod mechanism 3 is withdrawn, and the shelf board 2 can automatically return to its initial position under the action of its own weight.

[0043] Those skilled in the art should understand that the lifting height of the shelf board 2 is mainly determined by the connecting rod lifting mechanism 4. The connecting rod lifting mechanism 4 can not only adopt the lifting mechanism composed of four connecting rods crossed in the embodiment of the utility model, but also adopt the lifting mechanism composed of two connecting rods, six connecting rods, etc.

[0046] In summary, the adjustable angle logistics shelf provided by the utility model can lift the shelf board to a certain tilt angle under the joint action of the push rod mechanism and the connecting rod lifting mechanism, so that the goods can automatically slide out of the shelf to the picking device under the action of gravity. After the goods are taken out and the force of the push rod mechanism is withdrawn, the shelf board can automatically return to its initial position under the action of its own weight. Its shelf structure is particularly suitable for warehousing of packaged goods with large storage volume, consistent specifications and models, large external dimensions and heavy weight. Combined with the multi-layer shelf storage design, it can not only improve the utilization rate of storage space and save land resources, but also improve the operating reliability of loading and unloading equipment and the safety of goods.
